Original application tiled April 20, 1917, Serial No. 163,348. Divided and this application filed December 2, 1918. Serial No. 264,901.

- .To all whom it may concern:

Be it known that I, JOSEPH BLAUSTEIN, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in (1alciilating-ltlachines, of which the following is a specification.

This invention relates to that class of calculating machines in which disks having parallel axes are used and keys are employed for setting the machine for successive operations through sliding setting gears to be variably actuated by step gears, such machines being known as the Thomas type. The present application is a division of my application Serial No. 163,348 filed April 20, 1917, and more especially it relates to the key-setting mechanism by which the mem bers to be combined are set up in the operation of the machine to perform the desired calculation.

The objects of the inventibii are to secure accurate and positive action, quietness and ease of operation; to provide for each row of keys a swinging plate adapted to be operated by any one of them to actuate the setting gear; to combine with said swinging plate a sliding plate in translating the vertical movement of the keys into movement at right angles thereto; to actuate a checking evice or set-up-figure wheel directly from said sliding plate; to provide a swinging bar for holding "a key depressed and for releasing that key when another is depressed or when the cycle of operation is nished; to enable said bar to provide a single edge for engagement with all the keys in the row; to provide improved means for automatically releasing said bar from the keys at the completion of an operation of the machine; to. also provide erasing means operable either by hand or automatically for returning the swinging plate and slide plate to initial position; to secure a construction of sections one for each row of keys any one of which sections can be removed without removing either of the next adjacent sections; to at the same time secure a compact construction in which the rows ofkeys shall be near together; to secure a construction which can be economically and advantageously manufactured and in which the various parts are accessible for examination oradjustment, and to secure other advantages and results as may be brought out in the following description.

Referring to the accompanying drawin s, in which like numerals of rcference-indica te the same parts throughout the several views,

In said drawings, 1 indicates the base of the machine, 2 the walls of a casing built up on said base to contain the working parts, and 3, 3, etc., indicate sections of the upper part of the casing which carry each a row of setting keys 4. It will be understood that these sections extend from front to rear as the machine stands before the operator, each carrying keys with numerals from 1 to 9, and that there are as many sections in a series from right to left of the machine as may be necessary to give the machine its desired range of numbers.

Secured to the bottom or floor of the casing and standing edgewise therein is a casting 5, see Figs. 1, 2 and 3 especially, which extends from right to left of the operator and in which isjournaled a shaft 6 Ion itudinally of the casting and adapted to e rotated asdesired by a crank 7, as shown in 1* ig. G, at the right-hand end of the machine, to operate the machine in calculating. Said casting 5 also provides lower bearings 8 for step gear spindles 9 and upper bearings for setting gear spindles 11, see Fig. ing shoulder 28. It is to be understood that 1, which spindles extend rearward from the the keys of any one row are positioned all casting to operate the calculating and regat one side of that section 3, and the bent istering mechanism. There is one of each of portion 26 projects inwardly of the section said spindles for each section 3 of the mabeneath the top piece 17 of the casting and chine and each step gear spindle is conthe top plate 19. A stop 29 is provided nected to the shaft 6 by .bevel gears 12, 13. .on the key, preferably at one edge of the It is to the means for operating the setting same, to engage the under side of the plate gears 14 by means of the keys 4, pl'ellm m'y 19 and accurately limit upward movement to turning the crank 7 to actuate the ealcuf th k E h k h t it id lating mechanism, that the present mver site from the bent portion 26, that is, protion more particularly relates and which j ti away f th ti 3 a pm 30 will next be described. adapted when the key is depressed to engage The setting keys 4 project from the t ps a swinging plate 31 and operate the same.-

of the sections 3, see igs. 1, 2. 3. G and 7, This swinging plate (see Figs. 2 and 3 30 and are slidably mounted in said sections particularly and also Fig. 7) lies in edgewhereby they may be depressed, Pre c wise position longitudinally of the section ably said keys. as shown in Fig. 8, are, just outside the keys 4, being suspended by stamped out of sheet metal and provide links 32, 33 outside the plate near its opeach a foot 15 at its inner or lower end posite ends and which are pivoted to the top 5 and a shank 16 at its outer or upper end, piece 17 of the casting or frame of the see- .both said foot and shank extending longition. At its upper edge said swinging plate tudinally of the key, by means of which the 31 has recesses the rear walls 34 of which key may bemounted to slide longitudinally are inclined upwardly rearward and adapt of itself. The casting or frame work of ed to be engaged each by one of the keys each section 3 provides a top piece 17 and 4 or pins 30 thereon, so that as any key is a bottom bridge 18 spaced apart in substfifldepressed the swinging plate will be swung tially parallel relation. see Figs. 2. 3, (i endwise accordingly but will always remain and 7, and fiatwise upon the top piece is parallel to its first position. These rear secured a top plate 19, said top plates of walls 34 incline differently, each from the adjacent sections being contiguous at their others, so that the plate will be swung edges so as to close the top of the machine, more or less according to the key which is as shown in Fig. 1. A slot 20 is cut in the pressed. As shown in the drawings, the wall edge of the bridge and a slot 21 is cut in the 34 nearest the front of the machine which corresponding edge of the top plate for will be engaged by the first or front key each of the keys, the shank 16,0f the key slopes the least, that is, is inclined only riding in the slot of the top plate and the slightly out of parallel relation to the difoot 15 of the key riding in the slot of the rection of movement of the key, whereas the bridge of the casting. A strip 22. secured inclined wall for the last key has the greatto the edge of the bridge outside of the keys, est slope, and all of the intermediate rear 10 holds the feet 15 thereof within their slots, walls slope more and more from the first and the adjacent top plate 19 holds the to the last. By this means, the swinging shank portions of the keys in their respecplate will be moved a predetermined distive slots. In this manner, the keys are tance by any one ke andthe distance it slidably held so as to be free to move up is moved will be di erent for each key of and down, and preferably a spring 23 is the row.

provided to normally-slide each key up- The link 32 atthe rear end of the swingwardly, as shown, said spring being placed ing plate 31 extends downward beyond said upon the foot 15 and hearing at its lower plate and is provided with a lateral pin 35 end against the bridge 18 and at its upper which enters a slot 36 extending upwardly end againstea downwardly facing shoulder from the lower edge of a slide plate 37, see

24 at the upper. end of the foot 15. -Between Figs. 1, 2, 3 and 4 especially, said slide plate the upper end of the foot and the lower end preferably lying in the same plane with the of the shank of the key, the material is swinging plate 31, and having longitudinal extended laterally in the plane of the foot 'slots 38, 38 near its upper edge to receive sta- 1 and shank, as at 25, and at the outer end of tionary screws 39 projecting from the bridge this lateral extension the material is bent 18 of the section casting and u on which the on a line parallel to the foot and shank into' plate can slide. The front on of this slide a plane substantially perpendicular to that plate projects forwardly over the casting 5 of the extension. providingthereby a porand back of said casting the lower edge of tion 26 for purposes hereinafter described. the slide plate is in proximity to and paral- At the bottom of said bent portion 26 and lel to the setting gear spindle 11. The slide sloping upwardly toward its free edge is a plate carries an arm 40, see Figs. 1, 2 and 3,. downwardly facing shoulder 27, and at the transverse to the plate and extending betop of said bentportion is an upwardly fac neath the section, adapted to engage and 30 gamma slide a setting gear 14 upon its spindle 11. In the drawings, engagement of this arm with the setting gear is shown effected by positionin the arm in an annular slot be tween sai setting gear 14 and a locking gear 42 also movable with the setting gear, so that the arm 40 will move the setting ear longitudinally of its spindle as the side plate 37 moves, and carry said gear a greater or less distance according to which key is de pressed. It s to be understood that a step gear 43 is fast upon the corresponding step gear spindle 9, adapted to engage and turn the setting gear through a greater or less are, dependent upon the relative position of said setting gear longitudinally of its spindle, and thus turn said spindle. The manner of doing this and of preventing rotation of the settin ear spindle otherwise is fully set forth and escribed in m prior application above referred to, of w ich the present application is a division, and" need not be detailed here.

Inorder to hold any key of a row depressed, and to utilize the depression of that ey to release any other key previously depressed in that row, a swinging lock bar 54, see Figs. 9 and 7, extends longitudinally of the section adjacent the row of keys at the side thereof toward which the bent portions 26 of the keys project. This locking bar is pivoted adjacent its ends to swing bodily away from the keys, and as shown is made in a sort of angleron cross-section with one flange .rojecting toward the keys and the other ange provided with cars 55, 55 by means of which the bar is pivoted to the oposite ends of the section casting or frame. he flange projecting toward the keys is adapted to normally underlie the lower or downwardly facing sloping'shoulders 27 of all the keys, so that depression of any key will swing the bar. Further depression of the key brings its upwardly facing shoulder 28 below said flange of the bar, so that the bar may then swing in toward the keys again and hold that one de ressed. Should another key of that row hereafter be depressed, the bar is swung outward by the second key, thereby releasing the first one and permitting it to return to its initial osition. It will be understood that this ocking bar swings with very little friction and thus presents minimum resistance to depression of the keys.

Means are provided for swinging all the locking bars 54 of the machine after the setting of the registering mechanism, that is to say, near the end of the revolution of the crank 7 so as to release any keys which have been depressed, preparatory to pressing again for a further calculation, and for this )urpose I have shown upon the shaft 6, see igs. 1, 2, 3 and 6, a cam 56 which operates a bell crank lever 57 so as to slide from left to right of the machine a coinh 58 mounted upon the front wall of the casing, as by slots 59, 59 receiving screws 60, 60. This comb has at its upper edge teeth 61 adapted to engage the lower arms of levers 62 pivoted as at 63 one upon each casin section' and swing said levers so that their upper arms 64 wlll push the locking bars 54 away from the keys to release said keys and permit their springs to throw them into upper or normal position. Any other suitable mechanism maybe employed for thus releasing all the keys at the proper time, ready for settin up a new number, however.

11 conjunction with the release of the keys, and correspondingly timed therewith, I desire to have some erasing means operate positively to restore the swm ing plate 31 to normal position, and for this purpose I have shown a shaft 65 extending from right to left of the machine preferably just forward ofthe shaft 6 and provided with an arm 66 adapted to be engaged at the proper moment by a cam 67 on said shaft, see Figs. 1, 2, 3 and 6. This rocks the shaft 65 so that arms 68 fast upon the shaft, one for each section, will engage each a pin or projection 69 upon a swinging plate 31 and return them all tonormal or zero osition. Preferably such normal position 15 determined by means,of a stop 70 upon the section casting or frame adapted to engage the end of the slide plate 31, see Figs. 2 and 3. In case it should be desired to erase without any operation of the machine by its crank 7, the shaft 65 projects outside the casing, as shown in Figs. 1 and 6, and receives a hand'lever 81 by means of which the shaft can be rocked by the operator independentl of the operation of the machine b t e crank 7. Obviously in this case it 1s necessary also to swing the looking bars,54 and release the keys, and for this purpose the cam 67 on the shaft 65 has opposite its arm 66 a bent arm 82 which overlies the bell crank lever 57 which opcrates the comb 58, as clearly shown in Figs. 1 and 2. This insures that when the shaft 56 is rocked by the hand lever 81 the swinging and Slltllll" plates are not only returned to initial position, but also the keys 4 are released and elevated so as to )ermit such return of the swinging and sli ing plates.

In order to accurately aline all the setting gears of the various sections of the machine, each slicling. plate 37 is provided at any convenient point, such as the lower edge of its front end, with a series of Y- shaped notches 71 one for each of the ten positions which the sliding plate may occupy, see Fi 2, 3 and 4, and an alining bar 72, see igs, 1, 2 and 4, extends from right to left of the machine beneath said notches and has a correspondingly tapered upturned edge 78 to enter the same. Said a ining bar has arms 74, 74 at its opposite ends which are fastened upon a shaft 75 near the front of the machine and journaled in any suitable bearings u)onthe casing.- Said shafts75 is also provided with an arm 76 which extends rearwardly and is adapted to engage a cam wheel 77 upon the shaft 6, said cam wheel being arranged and adapted to throw the arm 76 upward soon after the shaft 6 begins to turn and hold it upwardnntil shortly before the shaft stops. This causes the alining bar to "enter whichever notches of the slide plates of the various sections are over it, as determined by the positions which the slide plates have assumed under the controlling influence of the keys, and thereby aline the slide plates and thus the setting gears with absolute accuracy, holding them so during the operation or until the alining bar is again lowered.

The end of each slide plate 37 toward the back of the machine may carry a rack 78,

as shown in Figs.'2, 3 and 5, which engages a gear wheel 79 connected to a setting-upfigure wheel 80, so as to display through sight holes in the'top plate 19 numbers corresponding to those for which the keys have been depressed and thus check the accuracy of the operation.

It is to be particularly-noted in my improved construction, that by removing the top plates on opposite sides of its row of keys, any section 3 may be lifted out of the machine, thus saving the tedious labor of removing all of the sections from one side of the machine to the one desired in order to remove it, as is customary in most of the present typesof machines. As there are no parts supported partiv from the sectionjlcastin and partly from the base. re. moval of tile section does not affect adjustments in any of the parts, nor will any parts be liable to damage by failure to loosen them before attempting to remove the sec tion;

In operation, the sliding plate 37 and swinging )late 31 of each section are initially at their forward or zero position, see Fig. 2. The number to be used in the calculation may then be setup by pressing the proper key in each row to its inner position, see Fig. 3. Depression of the key engages its laterally projecting pin 30 with the inclined rear wall 34 of the swinging plate 31, and continued depression of the key causes said plate to swing'in its own plane longitudinally of the row of keys. Depression of the key also engages the sloping. downwardly facing shoulder 27. thereof with the swinging locking bar 54. the key thereby pushing the bar aside and holding it thus swung until the key is entirely depressed to its innermost position, at which time said bar will swing back into its original position and engage above the upwardly facing shoulder 28 of the key and thereby hold the he in its depressed position. The swinging o the plate 31 by the key obviously causes the supporting links 32, 33 to swing also, and the link 32 through its slot and pin connection with the slidefilatelhmovcs said slide plate rearwardly. y virtue of the progressively increasing slopes of the successive rear walls 34 of the swinging plate, the swinging plate and slide late are moved further rearwardly by lieys nearer the rear of the ma chine than the front. Therefore, each key will slide the slide plate a predetermined distance different from any of the other keys. By virtue of the arm 40 carried by the slide plate, the setting gear 14 and locking gear 42 are also slid rearwardly upon their siindle 11 and the setting gear positioned in proper relation to the step gear +13 so that upon rotation of said step gear through a full revolution the proper rotation of the setting gear is obtained. It is to be understood that operation of the step gear to turn the setting gear is obtained after the keys have been depressed. by rotation of the crank 7, see Fig. 0, which rotates the shaft (3 and through the bevel gears 12, 13 the step gear spindles 9. As the crank is started to be turned, the cam 77 swin s the arm 76 upwardly. thereby lifting the al ining bar 72 to engage the same with the notches 71 in the slide plates 37 and very ositivcly and securely position each slide plate so as to obtain accurate alineiuent of the setting gear with respect to its stop gear, the alining bar operating upon all of the slide plates regardless of what key is depressed in any row. hurtliernlortn, the alining bar is held lifted in engagement with the slide plates until near the end of the rotation of the crank. at which time it is permitted to lower and the cam 36 operates upon the bell-crank lever 57, sliding the comb 58 and tripping the swinging lock bars 54 through the agency of the several levers 62. Swinging of these bars'permits the springs 23 on such keys as were depressed to actuate said keys outwardly, after which the cam 56 permits the hell-crank to swing back and the locking bars to also swing into their normal )osition underlying the sloping shoulders of tile keys. The other cam (i? will rotate the shaft 65 just after the keys are released and thereby causcthc arms 68 to swing forwardly and engage the pins (39 on the several swinging plates 31, pushing them forwardlyinlotheirinitial or zero positions and obviously sliding the slide plates 37 also back into their zero po-. sitions.

In setting up numbers, it will be seen that where one key of a row has been depressed and another key of the same row is afterward depressed this swings the locking bay;-

out again and thereby automatically releases the first key which was depressed and the locking bar will then swing in again to lock the last key down. It may be noted in this connection that the recesses formed in the swinging plates 31 have not only inclined rearward walls 34 but also have inclined front walls converging with respect to the rear walls toward the bottom of the plate, so that the recesses are substantially V- shaped. Since the positive alining is obtained by the alining bar 73 coacting with the slide plates 37, it is not necessary to have any vertical pockets at the bottom of these V-shaped recesses for alining purposes, and consequently any movement of the swinging late 31 one way or the other will positively orce any of the keys upward which are deressed at the time of that movement. For instance, in Fig. 3 one key is shown depressed, and if another key were now to be depressed and for any reason the spring on the one which is depressed failed to force it u ward when released by the bar 54, it is 0 vious that the second key being depressed would move the swingin plate 31 either toward the front or rear o the machine and as a conse uence either the front or rear inclined wal of the recess for the depressed key would wedgin ly engage the pin 30 thereon and force t e key' outward. It is therefore not possible in this construction, as occurs fre uently in other machines, that two keys wit in the same section could become accidentally jammed in a half-way position and thus lock the entire mechanism until repairs were effected.

Furthermore, the operator is enabled to check up the number which he sets up by means of the setting-upfigure wheels 80, which display the respective numbers for which the slide plates are set. Obviously, if throu h some inadvertence a slide plate is moved from its forward position without any key having been depressed, the setting up-figure wheel will show this, and the operator can remedy the error.
